Specification of Letters Patent.

Application filed October 1, 1917. Serial No. 194,174.

To all IIJ/1.0m. 'it may concern.'

Be it known that we, ABRAHAM KirNiss, a citizen of the United States, and a resident of the borough of Brooklyn, city of New York, in the county ot' Kings and State of New York, and MAX PAUL NEUMANN, a citizen of the United States, and a resident of the borough of Brooklyn, city of New York. in the county ot' Kings, have invented a certain new. and useful Machine for Making lobbins for Electric Batteries. of which the following is a specification.

"lhis invention is an improvement on a machine t'or shapingr carbon to bobbiii form for use in electric iatteries; for which we obtained a patent on January 2, 1917, No. 1,211.170.

The object oi the present invention is to provide automatic mechanism which will press powdered graphite, or any suitable de polarizing material, sufficiently to canse it to hold together and to cause a stick ot' previously pressed carbon forming an electrode rod to be eit'ectually secured therein. f

It has been learned by experience that is required tocompress the graphite than is required to cause the carbon stick to be retained therein, for which reason we have in the present invention provided means for pressing the graphite around a removable core, previous to the time the carbon stick is placed `in thus formed and for again pressing the graphite, so that this carbon stick Will be retained therein. 1 The invention consists of an -'i ntermit. tently rotating carrier provided With 'a series of compressing chambers which are successivelylled with powdered graphite from a' magazine; each of said filled chambers passing in succession beneath a series of graphite in. one of said Chambers; the` 'sec- 'ond of saidplungers 4adapted toA force a stick of previously pressed carbon into said hole in said pressed graphite; the third of said plungers adapted the' graphite in said chamber, and to said graphite around .said plunger having a recess 'f press carbon stick, the or receiving one end of said carbon stick, which end is thereby left protruclingbeyond the compressed and carbon stick the hole- -niaiii frame l of the said plungers adapted' ltocompress and pun'ch a hole through 'the tp vfurther compress to the lever and graphite; the fourth and last of saidlpluir gers adapted to force said pressed graphite out of said chamber and into one of `a series of receptacles forming part of an interniittently-moving conveyer adapted to move the bobbin thus formed away from said carrier.

for controlling the outlet of a magazine for previously pressed carbon sticks in different' position from that shown in Fig. b8.

Journaled in. suitable bearings on the `iachine is a shaft 2.

Loosely mounted on the shaft 2 is a pulley 3, the hub of which is -provided with teeth 4. In engagement with a spline 5 on shaft 2 is a sliding collar G having teeth 7 which are adapted for engagement with causes rotation of shaft 2,

Secured to one end of shaft 2 is' a crankarm 8`Which is connected by a 1ink.9 to a longer arm lO secured to a shaft 11, which shaft is thereby -g'ive'n a. rocking side of which is secuied a cam 13. Adapted for' engagement with cam 13 .is a roller 14 which is journaled-on` one end oa. Alever 15 pivoted at 16, the roller being held against said' cam byineal'is of a. spring 17 attached to frame 1. The other end oflever 15 is connected by a link 1R to motion. Secured to rock-shaft ll is a `disk 12, to one' mounted on a 2i) is` a dish 2l. nted in arm 19 iorced by springs y S .o ovided with is a sliding pm i cth which le 2l into engagement with one of said teeth 22, whereby partial revolution of shaft 2O is caused when lever is moved to the position shown in Figs. l, 3, 6, 7 and 8, by means of Cain i3. Secured to shaft 20 is a bevel gear Wheel in mesh With a bevel gear Wheel 26 hall" its diameter, Which is secured to a vertical shaft 27. -Tothe upper end of shaft 27 is secured a 'disk 28 having a lseries oi' hollow cylinders 29 located near its periphery and extending parallel vwith the vertical shalt The disk 28 rests upon a series of balls 30 which are supported on a base plate 3l attached to the main frame. The cylinders 29 are open at both ends, and the disl7 28 is so supportedby the vhalls 30 that the lower einen end of each cylinder barely touches the base-plate 3 1.

Ae shown in Figs. l and 6, a magazine 32 containing powdered graphite 33 is so placed' above the dish 8 that the outlet 34 oi the magazine 'is directly above one of the chambers formed by the interior of said cylinde 29, so that powdered graphite Will descend into said cliainber'to rest on said base-plate 3l. .K

The sliding' pin 23 has an inclined end 36 so that i en cam 13 permits return-movement ver l5 and arm 1,9, no movement will l' f, 'imparted to the shaft 20, 'gears 25 Aand shaft 27 and disk 2S. During rement of lever l5, the lovver end novas againstan incline 37 formed j the opposite' hooked. end Ll0 of said lever 38 to be thrown out of engagement with one of a series of teeth il which are formed on the periphery ofthe disk 28.-

"When return movement of arm 19 causes the sliding pin to engage another tooth 22, and another movementbf rock-shaft 1l again causes cam 13' tov actuate lever 15 and arm 19, another partial' revolution of shaft 20 will occnr, with the consequcntpartial revolution oi gears 25 and 26,01 vertical shaft 27 and disl; At the sametnne the move.

nient of leverl i5 permits movement of lever 38 by means olea-springe@ thereby causing the hooked end 4C thereo'i'to be moved into range with the teeth 41 of disk 28, so that when the disk is'rotated the distance caused by the cam 13 further movement; of the disk will be prevented. by the engagement of another of the teeth l with the end 40 of lever 38. A repetition of the operation of this mechanism by successive movementsofthevl ioclesliait ll causes the disk 28 tofcarry the graphite iilledehambere 35 of cylinders 29l successively to rest beneath 1a series of plungerslfil, t, 45 and i6 Whichextend down ward' from a. sliding cross-head 4a.

Croiss- 'diaineteiitllan the plunger.

d of a lever B8 pivotecl at 39, theredownward movement of `a head ai? is caused to reciprocate vertically in indes 4 8 by means of a Pitman i9 connected to a crank-pin forming part of cranks 5l which are-secured' to the driving ger 43 acts to compress the graphite against .the Wall of the chamber, against the basev plate, and against the core rod, as shown in Fie. 5.

5V hen cranks 5l :cause upward movement of the slide 4'? and consequent movement iof the plunger i3 from the position shownin Fig. 5 to the position shown in Figs. 3 and 4, crank arm 8 causes movement of rockshaft; 1l and cam 13, thereby actuating lever l5, which causes rotary movement of the disk 28 and consequent movement othe.

chamber 'B5 having the ressed' graphite with thehole 55 formed t .erein to rest beneath theplunger e4, as shown 'in Fig. 4.

.In line .with the lonitudinal axes of plunger 44 and hole 55 in said graphite, is a shaft 56 extending at right an les thereto, and having an attached arm 5 provided with a re` cess 58 in which a stick' of previously. pressed carbon 59isplaced,l therecess 5S being in line Witlra hole 60 extending through the shaft 56, as shown in Fig e. ln line with, 'the receso 58 of arm 57 is the outlet end of a chute which is inclined downward from a ma ezine 62 containing previously ipreseedea `on-st1cl;s 59. @ne

- of the carbon sticks is permitted to roll from the chute intothe rec'eesV 58 ofarm 57 by gate 63 .which rests on.'l one end of a lever gpivoted at'; The other end of lever Si, adapted. for enu gagement with an inolined lug'- 66 extending downward `from a barfwhieh'. isliree to 'slide' in guides 68. Tll'nppei; side of liar 67 is provided with ag'raclr 69 which is in mesh with a gear Wheel 70- secnred to the shaft 56. Secured tov bar 5T is an arm 7l, the end 'of which is adapted for engagement with an inclined` surface- .72, forming part 'of la slidingv bar 73,'the 'upper e'nd of' which .entendsin among the ,carbonstiolisjf inthe magazine 62l near 'the entrance'lte the chute y ,61, l Bar 67 is connected by a link le to one endfof a lever 7 5 pivoted 'at The 'other end of lever 75 is pivote'd `withstroller adapted for engagement-f with' a cani. snrface 78 formed on theperiplieryofthe disk in Fig. 3. The inclined lug 66 acting on lever 64 has then caused downward movement of the gate 63, the rack 69 acting on gear 70 has caused arm 57 to swing to the position shown in Figs. 4, and 8, so that a carbon stick 59 has moved into the recess 58, and arm 7l acting on lnclme 72 has permitted the bar 731:0 move downward,

thereby permitting the carbon sticks in the hopper l62 to move toward the entrance to the-'inclinedchute 6,1. Movement of rockshaft 11 in the opposite direction then causes cam surface 7S acting on roller 77 to actuate,

. lever 75, and 4thereby-,move slide G7 in the opposite direction, which causes arm 71 to act on incline `72 ofpbar 73 and thereby cause upward movement ofthe end of the bar in the hopper 62, whereby the carbon sticks are moved or' agitated so that they will readily roll into the chute 61; said movement of slide 67 causing inclined lug 66 to C act on lever 64 and thereby cause gate 63 to be raised to the position shown in Fig. 9, whereby the outlet of the inclined chute 61 is closed; said movement. of said slide 67 also causing rack 69 to actuate gear wheel 70 and thereby cause arm 57 and carbon stick 59. to be moved tothe position shown in Fig. 5 and by dotted lines in Fig. 4.

When cross-head 47 moves downward plunger 44 having a diameter' equal 'to the carbon stick 59 and forming part of said cross-head, is moved down through a guide in stationary part 52, and forces the carbon stick 59 through hole 60 ot' shaft 5G and down into the hole that has been formed in the graphite compressed in the chamber 35, as shown in Fig. 5.

lVhen 'cross-head 47 moves upward, another rotating movement of disk 28 carries the chamber 35 having the pressed graphite and carbon stick therein trom the position shown in Fig. 5 to the position shown in F ig. S, beneath the plunger 45; then when -plnnger 45 is provided with a recess 80 having the same diameter as the carbon stick and a disk 81 ot larger-.diameter which is forced by a spring 82 againstnshoulder 83,

`.and aac-ts during downward movement of the .adhere to the carbon stick and hold it securely in place. It will he seen that the portion of the carbon stick entering the recess 80 formed inthe plunger 45 is left protruding beyond the compressed graphite, when the plunger is moved to the position shown by dotted lines in Fig. 8.

Another upward movement of the crosshead 47 and rotary movement ot' disk 28 carries the chamber 35 having the graphite compressed around the carbon stick to the position shown on the let't hand side of Fig. 8 4and beneath the plunger 46. lVhen the cross-head again moves,downward, plunger 46 having the same diameter as the chamber 35 is moved down through a guide formed in stationary part 52. the lower end ot the its downward movement, to force the compressed graphite and car-bon stick, or bobbin as it may now be. called, out ot the compressing chamber 35 and into one ot' a series of receptacles 85 which are mounted on an endless chain 86 traveling over sprocket wheels 87 and 88. Chain wheel 87 is cured to a shaft 89 to which a ratchet wheel 90 is secured. Pivoted on shaft 99 is an arm 91 carrying a pivoted pawl 92 adapted tacle 85 to he moved into its position vbeneath the plunger 4G.

Secured to cross-head 47 is a nut 94 engaging a vertical screw 95 which is mounted on b'all hearings 96 and 97 in a stationary part 96 attached to the main'frarme. To the lower end of screw 95 is secured a cross-bar 99 having a plate 100 secured'to each end thereof, and extending downward into "the powdered graphite in magazine 32. During the vertical reciprocating movement of cross-head 47, the nut 94 acting on screw 95 causes an oscillating movementI of the plates 100, thereby acting as an agitator for the graphite in the magazine 32.

Also secured to cross-head 47 is an'arm v101 having one end of a screw 102 journaled .bobbin to be moved away and another recepend of an auxiliary magazine 104 for powdered graphite. To the lower end of screw 102 is. secured a bar 105 having a ding down into fue Verthe valve 108 is opened, Tube 198 is eonneoted by a, nk i!) "ao one enf of efe' l() which p'voted at lil.
